Earlier in the day, Saul had announced a $1.2 million haul on Twitter just four hours after Ryan was named as Romney's running mate.

Romney’s campaign moved quickly to fundraise after the announcement. An email sent shortly after Romney welcomed Ryan at a campaign
event in Norfolk, Va., asked supporters to “Donate $15 today to help restore
America's greatness and build a stronger middle class.”

But Democrats also are hoping to use the Ryan selection to
add to their own war chest.

President Obama’s campaign sent an email to supporters
saying that with his VP decision, “Romney doubled down on his commitment to
take our country back to the failed policies of the past.”

“Election Day is closer than you think — make a donation to
fund this campaign in the time we have left,” the note said.

The Democratic Congressional Campaign Committee (DCCC) sent
an email to supporters describing Ryan as “the architect of the Republican plan
to kill Medicare.”

Robby Mook, the DCCC executive director cited polling
showing that fewer than half of Americans had an opinion about Ryan and said
Democrats had to move quickly to inform voters about his budget plans.

Democrats have made Ryan’s budget, which would cut $5
trillion and make Medicare a subsidized private-insurance program, a
centerpiece of their attacks.

“We might not be able to out-spend Romney and the Koch
Brothers but we have to reach every last voter we can,” Mook wrote in the
email.

The fundraising fight sparked by Ryan’s pick comes after
Romney and the Republican National Committee (RNC) out-raised Obama and
Democrats for the third straight month, with a $101.2 million July haul,
topping the Obama campaign’s $74 million. It was also the second straight month
that the presumptive GOP nominee had passed the $100 million mark.

Those figures have raised concern among Obama donors that
they may be outspent in the next three months leading to the election, despite
efforts by the campaign to downplay fundraising expectations.

The Romney campaign, RNC and state groups have $185.9
million cash on hand.
